'The core of the company’s innovation is quantum-dot laser technology that can transmit more data at lower cost, using significantly less power. First conceived at Bell Northern Research (predecessor to Nortel Networks), quantum-dot lasers are designed using self-assembling nanomaterials that exhibit unique behaviours referred to as “quantum effects.”

“Usually, lasers can generate only one wavelength,” Arabzadeh explains. Quantum-dot lasers, on the other hand, are made up of millions of nanoparticles of different sizes, with like-sized dots emitting their own wavelength of laser light. “What you end up with is many wavelengths coming from a single laser source.”

“It’s gone through its next phase of evolution with RANOVUS,” Arabzadeh says. “The laser would not work if deployed today on its own. What we have had to include is all the other things around it to make it work.” ' ______________________________________________
